But the trip saved Hailie’s life. She was born on Feb. 23, 2017, weighing 1 pound, 2 ounces. By that point, Hailie was 23 weeks and 6 days along, just one day before the legal abortion limit in England.

The little girl battled through a collapsed lung and other ailments before she was well enough to go home.

“I’m so proud of her, what we’ve been through and what she has been through has been horrendous,” Price said.

Late last year, the journal Pediatrics highlighted a baby girl in the United States who survived after being born 21 weeks and four days after conception. The girl, now 3, is believed to be the youngest premature baby to survive.

A Duke University found babies born at just 23 weeks gestation are surviving outside the womb at a greater rate than ever before. Researchers examined 4,500 babies between 2000 and 2011 and found a “small but significant drop in fatalities for babies born between 23 and 37 weeks gestation,” as well as a decrease in premature babies manifesting neurophysiological problems, the Daily Mail reported.

These advances are prompting calls in the UK and United States to create earlier abortion limits to protect viable unborn babies.
